What is the difference between the anti-virus plug-in and the attachment filtering plug-in?
Antivirus (AV) software is signature-based, and therefore detects known viruses and trojans. Brand new viruses are not detected as there is no signature yet. That is where the attachment filtering (AF) comes in. We are able to block executable-type attachments regardless of what they are called or if they are renamed, allowing for admins to have a 100% detection and removal of possible malicious attachments while at the same time allowing policy level exceptions for outbound and internal traffic. The AV and AF plug-ins together are highly effective, with extremely low overhead.
